DfI'IoLLANn, or CHICAGO, InLnoIsf l gasoline engine between theF carburetor and the engine cylinders, and which has for its object the complete vaporization of the heavier components of the fuel, which otherwise would enter the explosion chamber in It is well known that most of the liquid fuel now commercially 's old as gasoline for use in automobile .enginesl andother motors contains a relatively higher percentage of the heavier hydrocarbons, such as kerosene, than was formerly the case, and that with the various forms of carbureters in general use these heavier constituents of the fuel chargel are only atomized and in large part are noty yolatilized, and therefore pass fromthe carbureterinto the intakeymanifold and engine cylinders in the form of minute, liquid particles which collect uponI the walls of the cylinder/y and mix with. the oil used for lubricating purposes, thus being lost tothe explosive mixture and acting to dilute the ,oil used for lubricating purposes. The ob-` ject of my invention is the production ofa y highly eflicie'nt vaporizing device which will' 35 act to permit the vaporized or, gaseous portion ofDthe mixture issuing from the car bureter'I to p ass to the intake manifold with -out impinging on heated surfaces and being x rarified,-thus reducing its volumetric etliciency,-but which 'will causel the liquid particles to be thrown against heatedwalls `Where they will be volatilized and then pass with Ythe ,first-mentioned 'unheated gas portion into the intake manifold and combustion chambers of the-engine. With this object in viewV I have desi ed and invented the novel vaporizing device hereinafter described, and which is illustrated in certain figures of the accompanying drawings and which constitutes a preferred form of my invention, and have Yalso \devised certain drawing.

'In the appended claims I have more `par. ,tlcularlypointed out the essential elements of my invention, it being understood, how.- ever, that still other modifications, besides those shown, are possible within the spirit of my invention and the scope of the claims.

In the drawings, Figure 1 is a View showing i'nvertical` section the preferred form of my novel vaporizing device, connected to` a carbureter and intake manifold of'wellknown form, portions of the associated parts vbeing shown in elevation; Fig. 2 is a horizontal section through the center of the device; Fig. 3 is a central vertical section of a'modiied form of my invention; Fig. 4 is a plan view of the deecting fan member of lthe same detached; and Figs. 5 and 6 are respectively a sectional view of a portionv of the inlet side, and a top plan view of the ldeflec'ting memberof a second modificationy of my invention. f y

The same reference characters indicate the same parts in all the figures of the As shown in/Fig. 1, the" casing of my vaporizing device is formed with double walls, the outer lwall land inner wall 2 uniting at the inlet side of the device to form a short tubular partition, orneck 3, and being joined at the outlet side by a 'similar tubular neck 4. The chamber 5 Within. the inner wall 2 of the device is i-n communiinvention l ywhich vare cation through the neck S-adjacent which is arranged a deflectingA member, vhereinafter described-,with the carbureter 6, and is in open communication, through the neck 4, with the intake manifold 7 of the engine. In the present instance the ,device is secured to the upper fiange 8 of thefcarbureter by means of bolts 9. passing throughafspacinu block 10 and engaging screw-threaded socketsr11 formed in solid. portions ofthe body of the vapori'zing device adjacent the neck 3, and the outlet side of the device is secured to the intake manifold by4 headed bolts 12 engaging an orifced flange 13 at the lowerend seated in screw sockets 14 neck4. e

formed in the casing body adjacent the particles .dashes them against .the hea-ted inner wall of the casing resulting in a vaporization` of the liquid particles and a i designed relatively direct unheated How of the initiallyy gaseous portion ofthe mixture similar'to that which takes place inthe forms of my invention already described.

ile my novel vaporizing device is primarily for -use upon engine employing as fuel the mixture of ylighter and heavier hydrocarbons commercially sup- (plied as gasoline, it will be understood that it may be applied to en es employing other and heavier grade of el which are either partlyvatomized and partly vaporiz'ed, or are atomized only, by means of a suit-able carbureting device, the capacity of the device land the amount of heatsupplied to it bein increased according to theidensity of the giel I claim: y v
